Iridium Complexes of a Triazole‐Derived Pincer Ligand: Synthesis, Reactivity, and Transfer Dehydrogenation Catalysis

open access: yesChemistry – A European Journal, EarlyView.
Ir pincer complexes bearing a triazole architecture in the pincer backbone and O‐ancillary chelating ligands are presented. These were employed in the catalytic transfer dehydrogenation of alkanes as well as of saturated heterocycles. Reactivity of these complexes with silver salts and Lewis acids produced various cationic iridium complexes.

A Low‐Symmetry FeII Tetrahedron From a Flexible Tritopic Ligand

open access: yesChemistry – A European Journal, EarlyView.
A highly symmetric and flexible tris‐bidentate tritopic ligand forms an S4 meso homoleptic face‐capped FeII tetrahedron near‐quantitatively in acetonitrile. The addition of nitromethane solvent causes partial isomerization of this meso cage to the racemic homochiral tetrahedron, with the complexity of the system being moderated through solvophobic ...
